Work vehicle

Abstract

A work vehicle includes an engine, a cooling device, a cooling fan unit, and a regulating member. The cooling device includes a radiator core. The cooling device is disposed facing the engine. The cooling fan unit includes a cooling fan and is disposed between the engine and the cooling device. The regulating member is disposed above the cooling fan unit and regulates the movement of the cooling fan unit in the horizontal direction.

 an engine; 
 a cooling device including a radiator core, the cooling device being disposed facing the engine; 
 a cooling fan unit including a cooling fan and a fan bracket supporting the cooling fan, the cooling fan unit being disposed between the engine and the cooling device, the fan bracket being smaller than the cooling fan in an up-down direction of the work vehicle; 
 a regulating member disposed above the fan bracket of the cooling fan unit when the cooling fan unit is in an installed state, the regulating member regulating movement of the cooling fan unit in a horizontal direction when the cooling fan unit is lifted upward. 
 
     
     
       2. The work vehicle according to  claim 1 , wherein
 the cooling device further includes a frame member supporting the radiator core, 
 the regulating member is attached to the frame member, and 
 the fan bracket is attached to the frame member below the regulating member. 
 
     
     
       3. The work vehicle according to  claim 1 , wherein
 the regulating member regulates the movement of the cooling fan unit in a direction approaching the radiator core when the cooling fan unit is lifted upward. 
 
     
     
       4. The work vehicle according to  claim 1 , wherein
 the frame member includes
 a left pillar portion positioned to the left of the cooling fan when viewed from the engine toward the cooling device and 
 a right pillar portion positioned to the right of the cooling fan, and the regulating member includes 
 a first left regulating portion attached to the left pillar portion and 
 a first right regulating portion attached to the right pillar portion. 
 
 
     
     
       5. The work vehicle according to  claim 4 , further comprising
 an attachment member 
 attaching the fan bracket to the left pillar portion and the right pillar portion. 
 
     
     
       6. The work vehicle according to  claim 5 , wherein
 an interval in a left-right direction of the work vehicle between the first left regulating portion and the first right regulating portion is smaller than a width in the left-right direction of the fan bracket. 
 
     
     
       7. The work vehicle according to  claim 5 , wherein
 an interval in the up-down direction of the work vehicle between the first left regulating portion and the fan bracket is less than a dimension in the up-down direction of the fan bracket, and 
 an interval in the up-down direction between the first right regulating portion and the fan bracket is less than the dimension in the up-down direction of the fan bracket. 
 
     
     
       8. The work vehicle according to  claim 5 , wherein
 the fan bracket includes
 a first surface that faces the radiator core and 
 a second surface that faces the engine, and 
 
 the first left regulating portion and the first right regulating portion are positioned further to a radiator core side than the first surface in a direction from the engine to the cooling device. 
 
     
     
       9. The work vehicle according to  claim 8 , wherein in a direction from the engine toward the cooling device,
 an interval between the first left regulating portion and the first surface is less than an interval between the cooling fan and the radiator core, and 
 an interval between the first right regulating portion and the first surface is less than an interval between the cooling fan and the radiator core. 
 
     
     
       10. The work vehicle according to  claim 4 , wherein
 an interval in a left-right direction of the work vehicle between the first left regulating portion and the first right regulating portion is larger than a diameter of the cooling fan. 
 
     
     
       11. The work vehicle according to  claim 4 , wherein
 the first left regulating portion has a planar shape that extends rightward in a left-right direction of the work vehicle, and 
 the first right regulating portion has a planar shape that extends in a leftward in the left-right direction. 
 
     
     
       12. The work vehicle according to  claim 4 , wherein
 the regulating member further includes
 a second left regulating portion attached to the left pillar portion in a position higher than the first left regulating portion and 
 a second right regulating portion attached to the right pillar portion in a position higher than the first right regulating portion; 
 
 an interval in the up-down direction between the first left regulating portion and the second left regulating portion is smaller than a dimension in the up-down direction of the fan bracket; and 
 an interval in the up-down direction between the first right regulating portion and the second right regulating portion is smaller than the dimension in the up-down direction of the fan bracket. 
 
     
     
       13. The work vehicle according to  claim 4 , wherein
 the first left regulating portion and the first right regulating portion have an elongated shape in the up-down direction. 
 
     
     
       14. The work vehicle according to  claim 4 , wherein
 each of the first left regulating portion and the first right regulating portion has an L-shape formed by a support portion and a contact portion, the support portion extending toward the engine in a front-back direction of the work vehicle and the contact portion extending inward toward the cooling fan in a left-right direction of the work vehicle, the contact portion being arranged to regulate movement of the cooling fan unit in the horizontal direction when the cooling fan unit is lifted upward. 
 
     
     
       15. The work vehicle according to  claim 4 , wherein
 each of the first left regulating portion and the first right regulating portion has an C-shape formed by a support portion and two contact portions at opposite ends of the support portion, the support portion extending toward the engine in a front-back direction of the work vehicle and the contact portions extending inward toward the cooling fan in a left-right direction of the work vehicle, the contact portions being arranged to regulate movement of the cooling fan unit in the horizontal direction when the cooling fan unit is lifted upward.
